cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regs

Browse source 
CPUState::gdb_num_regs replaces num_g_regs.
CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS.

Allows building gdb_register_coprocessor() for xtensa, too.

As a side effect this should fix coprocessor register numbering for SMP.
